Description

[Detailed explanation of the invention] [Industrial field of application] This invention is designed to be installed in a place where there are trees nearby in order to prevent situations such as tree branches coming into contact with the cable and damaging the cable. Related to cable protection covers that partially cover cables such as telephone lines and electric wires.

[Conventional technology]

As a conventional cable protection cover, there is one shown in Fig. 3. This item consists of a cylindrical body 50 made by cutting a pipe or tube made of polyvinyl chloride resin to a predetermined length, and when in use, a cable C and a wire W disposed along the cable C are inserted through it.
Moreover, it was suspended from the wire rod W.

[Problem that the invention attempts to solve]

However, the conventional cable protection cover is made of wire material W.
If the contact area between the cylindrical body 50 and the wire W gets wet due to rain, drops from tree branches, leaves, etc., water will adhere to the contact area and will not dry forever, especially when the end of the cylindrical body 50 and the wire W The contact area remains wet for a considerable period of time even after the rain has stopped. On the other hand, since steel wire is used for the wire rod W, if the above-mentioned contact area remains wet, red rust due to rusting of the wire rod will flow and become unsightly, and in severe cases, the strength required for the wire rod W may be reduced. There was a problem that the wire rod W could no longer be maintained and had to be replaced at an early stage. This occurs because the inner surface of the cylindrical body 50 directly contacts the wire W and the ventilation inside the cylindrical body 50 is poor.

The present invention was developed in view of the above circumstances, and it prevents the cylindrical body, which is a cable protection cover, from coming into direct contact with the wire rod, and also improves the ventilation inside the cylindrical body. To provide a cable protection cover capable of quickly drying a contact part with a support even if the contact part gets wet.

[Means for solving problems]

In order to achieve the above object, the present invention uses a cylindrical cable protection cover made of a hard synthetic resin net, and attaches the cylindrical body to the wire rod disposed along the cable at a predetermined distance. The key-shaped corner of the support having a wire holding part with a C-shaped cross section that opens downward and a key-shaped corner for attaching the support in the axial direction is inserted into a plurality of locations of the mesh in the axial direction of the cylinder. It was. In addition to the above-mentioned configuration, the present invention divides the cylinder at one point in the circumferential direction, and pushes open the divided area to easily insert existing cables and wires arranged along the cable into the cylinder. can be put,
Moreover, since the wires are visible through the mesh, the protective cover can be installed quickly and reliably.

[Effect]

Since the main body of the cable protection cover constructed in this way is a mesh body, the inside of the cover is always well ventilated, water does not accumulate, it is lighter than conventional pipes and tubes, and the cable protection cover and wire rod are is provided by inserting the key-shaped corner part of the support having a wire holding part having a substantially C-shaped cross section opening downward into a plurality of locations in the mesh in the axial direction of the cylinder. Since the distance between the wire rods and the wire rods is maintained, the moisture adhering to the wire rods also dries in a short time due to the fact that the cover is made of a mesh body, and rusting of the wire rods can be suppressed. Moreover, as a protective cover for the cable, it can completely prevent contact with tree branches, etc.

〔Example〕

FIG. 1 is a side view of a cable protection cover showing an embodiment of the present invention, in which 1 is a cylindrical body serving as the main body of the cover, which is made of a hard synthetic material such as high-density polyethylene, polypropylene, or polyvinyl chloride. This net is integrally molded by continuously extruding resin.
The cylindrical body 1 has a substantially cylindrical shape and has small holes all over its cylindrical wall, and the axial horizontal strands 11 constituting the net are in the form of ribs that protrude inwardly and outwardly from the circumferential wall of the cylinder. This transverse strand 11 is particularly strong against bending stresses in the axial direction of the cylinder, so that the net does not tear or bend due to contact with trees. The diameter of cylinder 1 is 60
mm to 120 mm, the mesh size is approximately 5 to 8 mm, the horizontal strand 11 is approximately 8 to 10 mm, the vertical strand 12 is approximately 2
~2.5mm.

Further, as can be seen from FIG. 1, the cylindrical body 1 is divided into left and right parts at the bottom, and numeral 2 indicates the split. The crack 2 serves as an entrance into which a cable 4 such as an electric wire or a telephone line and a wire 5 disposed along the cable 4 are inserted into the cylindrical body 1.
The width of the horizontal strands 11a and 11'a closest to the crack 2 is larger than that of the other horizontal strands 11 because when opening the crack 2, the horizontal strands 11a and 11'a are held and pushed. It is designed so that it can be easily pushed open. After opening the crack 2 and inserting the cable or wire, the crack 2 is returned to its original position and stopped using a U-shaped stopper 7. The stopper 7 has expanded portions 9, 9' at its tips, which are pushed into the mesh to prevent the crack 2 from opening due to wind, tree branches, etc. On the other hand, the cable 4 is suspended from the wire 5 by a suspension line 13. Although the wire rod 5 is made of galvanized steel wire or the like and subjected to rust prevention treatment, it will gradually rust over many years.
In order to prevent rust from occurring as much as possible, the present invention uses supports 6 to reduce the number of objects that come into direct contact with the surface of the wire 5 as much as possible. That is, the support 6 is composed of a wire rod holding part 6b having a substantially C-shaped cross section that opens downward, and two key-shaped corners 8, 8 projecting upward from the back surface of the wire holding part 6b. As shown in FIG. 2, the portion 6b is
The width D is approximately 20 mm, and small protrusions 3a are formed at three locations approximately in the center of the inner surface. Therefore, the wire 5 is securely fitted and held in the C-shaped wire holding part 6b of the support 6, and is supported by contacting only the small protrusion 6a in the wire holding part 6b. This wire 5
The water droplets will not remain stuck on the surface forever and will dry faster. Further, the tips of the two key-shaped corners 8, 8 protruding upward from the back surface of the wire holding part 6b of the support 6 are inserted into the mesh of the cylinder and locked, and are held against the wire 5. The inner wall of the cylindrical body 1 is attached so as not to come into contact with the inner wall thereof. Both the support 6 and the stop 7 can be easily obtained by injection molding synthetic resin such as polyethylene or polypropylene.

[Effect of idea]

As explained above, the cable protection cover of the present invention provides a predetermined distance between the cylindrical body serving as the protective cover and the wire that is securely fitted and held in the wire holding portion of the support, which has an approximately C-shaped cross section. Since the cylinder is made of a net, good ventilation inside the cylinder is maintained, and water does not accumulate in the contact area between the wire and the support of the cylinder. First, the contact area dries much faster than before. Therefore, even if steel wire is used for the wire, the wire is less likely to rust, extending its service life, and at the same time eliminating the unsightliness caused by red rust leakage.
Since the wire is firmly held in place by the support,
The cylinder does not move.

In addition, since the cylindrical body that forms the main body of the cable protection cover of the present invention is obtained by continuous extrusion molding of synthetic resin such as polyethylene or polypropylene, the main body of the cover can be formed by simply cutting it to a predetermined length. It also has the advantage of being extremely cheap to make. Moreover, the cable protection cover of this invention is strong because it is made of a hard synthetic resin net.
It is not easily damaged by tree branches hitting the cable during rainstorms, etc., and is extremely lightweight, so it has the advantage of being able to be installed efficiently at high places. .
